时差N小时:大豆和前列腺
雅艾尔：想喝点豆浆吗，唐?
Don: I'll pass, thank you.
唐：不用，谢谢。
Yael: What about some of this tofu salad?
雅艾尔：来点豆腐沙拉怎么样?
Don: Why are you pushing soy foods on me?
唐：为什么你老是向我推荐豆制品?
Yael: Because it turns out that there is yet anotherbenefit to consuming soy, and this benefit is formen specifically. When digested, soy creates amolecule called equol, which blocks the male hormone dihydrotestosterone, otherwise knownas DHT.
雅艾尔：因为事实证明食用豆制品另有益处，对男人更是如此。在消化时，豆类会产生一种雌马酚分子，这种分子会阻碍男性分泌DHT(双氢睾酮激素)。
Don: Hold up there. Why on earth would I want to consume something that will block myprecious male hormones? Aren't those important?
唐：等一下。到底为什么我要吃这种对我宝贵的雄性激素有害的东西?我的性激素难道不重要吗?
Yael: Down boy! Testosterone does serve important functions, but DHT is not so desirable,considering its involvement in prostate cancer. The pharmaceutical industry has focused a lotof energy into developing drugs that do what soy does naturally. Except the problem is that thedrugs created to fight prostate cancer don't just affect DHT, but they affect testosterone too.These drugs inhibit testosterone from converting into DHT. In doing so, they not only reducethe harmful effects of male hormones, but they reduce the beneficial effects of thesehormones too.
雅艾尔：坐下，伙计!睾丸素的功能的确很重要，但考虑到它与前列腺癌有关，DHT就不那么值得拥有了。制药行业集中大量精力投入到开发药品上去，但得到的效果与天然的大豆相差无几。但有一个问题，用来抵抗前列腺癌的药物不仅会影响DHT,还会影响睾丸素。这些药物阻止睾丸素转化为DHT。这样，它们虽然减小了雄性荷尔蒙的有害影响，但也阻碍了这些激素的有益影响。
Common side effects of these drugs include reduced libido, impotence, decrease in musclestrength, and an increased risk of osteoporosis. What's so promising about soy is that itdoesn't prevent the conversion of testosterone into DHT, but instead blocks DHT fromfunctioning once it's made. The result is that soy prevents DHT from doing its damage withoutblocking the beneficial effects of male hormones. Scientists think that because of its effects onDHT, soy may prove beneficial in treating other conditions associated with DHT, such as malepattern baldness.
这些药物的副作用通常包括降低性欲，阳痿，肌肉无力，增加骨质疏松的风险。大豆前景那么广阔的原因在于它并不阻碍睾丸素转换为DHT，恰恰相反，它阻碍DHT发挥应有的作用。因此大豆能防止DHT危害人体，同时保证雄性荷尔蒙对人体的有益影响。考虑到大豆对DHT的影响，科学家们认为大豆可能有利于治疗其它与DHT有关的病症，例如男性模式脱发。
Don: On second thought, how about you pass that tofu over this way?
唐：经过重新考虑，你还是把豆腐递到这边来吧。
